<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">one less malloc == faster and less fragmented memory and you dont' have to worry about the memory at all.</p></pre>

So I made it a pointer.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">But it's not like there's any need of management for it, it's simply created in constructor and deleted in the destructor, nothing else to worry about.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">That's not a problem, just initialize it in the initializer list of the ctor.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Concerning the discussion on the management: I personally prefer QScopedPointer for cases like this as it's just something less to worry about and ideally you can get in a situation where one can use the default dtor which (at least I have read so) is more optimized than a written one.</p></pre>

This patch rewrites the notifications so that all actions such as show/reposition/hide are handled from a one single place and every action is properly queued and protected around, which makes it more robust, more predictive and less chaotic. There's also a slight delay between every action so it's also visually much more cleaner and easier to see what's going on. </p></pre>
